Is it possible to have a multiple values to aggregate?

I was thinking if it's possible to have aggregator on multiple columns.

For example:

A | B | C
One | 1 | 2
Two | 1 | 2
One | 1 | 2
One | 1 | 2
Two | 1 | 2

rows: ['A']
vals: ['B', 'C']

average on B and sum on C

Something like that:

I know it will become rendering problem with graphs....but not so difficult for tables.

It will be a great plus!
